Restrictions for Simple data type [message #1852110]

Hello!

I try to import XSD in papyrus ang generate uml papyrus model from imported xsd.
First of all, I create genmodel (+ecore) from imported xsd.
Then I create uml model from genmodel (and then papyrus model from uml model).

Some simple types in xsd have restrictions (like pattern, maxLength etc).
I can see these restrictions in ExtendedMetaData in ecore file.
But in UML and in papyrus models all these restrictions had lost.

What should I do to import these restrictions in UML model from ecore?
Or if it is not possible to do it with the standard tools, what is the right way to create restrictions on simple data types in papyrus?

Hi Polina,
first of all XSD (standardized by W3C) is not an XMI (standardized by OMG) based format and for that reason cannot be imported by the plain vanilla Papyrus. But you can roll on your own importer.
Furthermore XSD sequence semantics cannot be directly mapped to the UML set semantics without information loss. Simply because the XSD sequence semantics has an element order, the UML set semantics has not.
The restrictions could be expressed by a profile applied to the UML meta-class DataType. The profile might also include an order number to mimic the XSD sequence semantics.
